| 摘 要： | 分布式发电以其调峰性好，起动和停止快，便于灵活调度等特性，是大型集中式单一供电系统的重要补充，结合微电网进行应用，十分适合在传统的大型电力供应系统出现故障或停电时充当紧急备用电源。本文以一套实际搭建的基于分布式光伏电站的微电网后备电源系统为研究对象，对其工作性能及特性进行了测试和研究。测试结果表明，本光伏微电网后备电源系统在实现光伏发电优先利用功能的同时满足了并网模式和离网模式之间平滑切换的技术要求。

| Abstract: | Distributed generation （DG） is an important supplement of the large-scale centralized single power supply sys-tem for its outstanding peak load regulating performance, controllability of quick start and stop, and flexible scheduling features. Applied in combination with micro grid, DG is very suitable to be the emergency standby powers for the public power grid when it fails. This paper describes a micro grid backup power supply based on the distributed PV system, whose performance and characteristics are also investigated in this paper. It is demonstrated in tests that the micro grid backup power system based on the DG PV system functions well in prioritizing the utilization of PV power, as well as the smooth switching between on-grid and off-grid modes. |
